Prenatal craniofacial development: new insights on normal and abnormal mechanisms
1Dental Research Center, School of Dentistry, University of North Carolina, Chapel Hill 27599, USA.
Summary
Advances in understanding prenatal craniofacial development reveal complex gene and cell interactions. Research highlights molecular genetics and animal models for birth defects like cleft lip and palate, offering insights into prevention.
Area of Science:
- Craniofacial Development
- Developmental Biology
- Molecular Genetics
Context:
- Technical advances are transforming our understanding of prenatal craniofacial development.
- Key areas include germ layer formation, neural plate patterning, and head segmentation controlled by homeobox genes.
- Neural crest cell migration and interactions, mediated by growth factors and signaling molecules, are crucial for craniofacial morphogenesis.
Purpose:
- To review current understanding of prenatal craniofacial development, focusing on molecular and genetic mechanisms.
- To explore insights gained from animal models of human craniofacial malformations.
- To discuss the multifactorial etiology of conditions like cleft lip and palate and potential research directions.
Summary:
- Modern techniques offer new insights into craniofacial development, including neural crest cell roles and signaling pathways.
- Animal models for fetal alcohol syndrome and retinoic acid syndrome illuminate neural crest cell involvement in malformations.
- Cleft lip/palate pathogenesis is often multifactorial, involving genetic variations and environmental factors, with implications for dentofacial deformities.
Impact:
- This review enhances understanding of normal and abnormal craniofacial development at a molecular and genetic level.
- It provides a foundation for investigating the causes of congenital craniofacial anomalies.
- Future research directions, including prevention strategies for craniofacial malformations, are highlighted.

01:30Neurulation
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the anterior...
01:29Bone Formation by Intramembranous Ossification
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...

01:08Overview of the Skull
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

01:07Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
01:28Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
